Answer: The answer is 4.

Step-by-step explanation: The way I got my answer was by isolating the variable by dividing each side by factors that don't contain the variable. I also have a website that you can use to help you! (if you want it, just ask me and I can provide it to you!)

I hope this info helps you! :D
